Gene-based therapies for tissue regeneration involve delivering a specific gene to a target tissue with the goal of changing the phenotype or protein expression profile of the recipient cell; the ultimate goal being to form specific tissues required for regeneration. One of the principal advantages of this approach is that it provides for a sustained delivery of physiologic levels of the growth...

Pulpotomy in deciduous teeth is a controversial issue, especially with regard to alternative materials used for the direct pulp capping of the root canal pulp tissue. The aim of the present study was to perform a histological analysis of the initial reaction of the root canal pulp tissue in rats, following pulpotomy and pulp capping with (1) green propolis extract, (2) iodoform paste, (3) green...

Dental pulp-capping is done to preserve vital teeth when the pulp exposed due caries, trauma or instrumentation. Various materials are used as agents. The introduction of newer requires scientific studies assess their clinical efficacy. study was designed a split-mouth randomized analysis four agents (calcium hydroxide, mineral trioxide aggregate (MTA), Biodentine and EndoSequence root repair m...

OBJECTIVES The objective was to evaluate the response of human pulps capped with different components from a total-etch three-step adhesive system. METHODS Direct pulp capping was performed in 25 caries-free human premolars scheduled for extraction due to orthodontic treatment. The teeth were randomly divided in five groups, and capped with the following materials: Group 1-acid+primer+adhesiv...

INTRODUCTION This study was conducted to compare human pulp response to mineral trioxide aggregate (MTA) and a novel endodontic cement (NEC) when used as pulp capping materials after a time period of 2 and 8 weeks. METHODS Thirty-two premolar teeth that were scheduled for extraction for orthodontic reasons were exposed and capped with either MTA or NEC. Half of the specimens underwent extract...

INTRODUCTION This study was carried out to investigate calcific tissue formation against mineral trioxide aggregate (MTA) after pulp capping. MATERIALS AND METHODS The pulps of six teeth from four dogs were exposed and capped with MTA. After extraction each tooth was sectioned into halves. Each half was then further sectioned in the mesiodistal or buccolingual direction. Calcified tissue of t...

introduction: the aim of this study was to determine the histologic effect of low level laser therapy (lllt) with or without the use of mineral trioxide aggregate (mta) on exposed pulp tissues of dogs. methods: twenty-five premolar teeth in three healthy mature dogs were randomly divided into five groups. in group 1, the pulp tissue was capped with mta. in groups 2 and 3, before capping with mt...

BACKGROUND Enzymatic degradation of plant biomass requires a complex mixture of many different enzymes. Like most fungi, thermophilic Myceliophthora species therefore have a large set of enzymes targeting different linkages in plant polysaccharides. The majority of these enzymes have not been functionally characterized, and their role in plant biomass degradation is unknown. The biotechnologica...

Over the last decade, the use of ethylenediaminetetraacetic acid (EDTA) has increased by a factor of three within the Swedish pulp industry. The effects of pulp mill wastewater in combination with EDTA on metal mobility and the consequences for ecologically relevant organisms have been studied. Ethylenediaminetetraacetic acid was added to pulp mill effluent water in the laboratory and compared ...

Use of switchable ionic liquid (SIL) pulp offers an efficient and greener technology to produce nanofibers via ultrafine grinding. In this study, we demonstrate that SIL pulp opens up a mechanically efficient route to the nanofibrillation of wood pulp, thus providing both a low cost and chemically benign route to the production of cellulose nanofibers. The degree of fibrillation during the proc...
